Research Abstract

The real-time displacement measuring system with digital image correlation method was developed and the displacements of three road-bridges and a railway-bridge were measured under traffic loaded state. The 2D movement of 32x32 partial image could be traced with better than 0.05-pixel resolution by image correlation method. The displacement measurement of the bridge was carried out at the interval of 50 times in a second. In the measured bridge selection, Sakae-Bridge was chosen as a big sample and one small bridge as a small one. The high-speed camera with 1280x1024x8bits resolution power was used in the measurement. The displacement of bridges coursed by the traffic load could be detected with enough resolution power.
